Such weighing-appliance is particularly conducive in the fork lift truck that is installed in the transportation chassis, promptly constitutes an integral body with fork truck.
When loading and/or transport the chassis, wish very much to understand the weight that is positioned over the goods on the chassis certainly.For this purpose, fixedly scale of a U-shaped that lays flat on one's back is arranged, like this, the fork truck that has loaded the chassis sails that , And is placed on goods on the arm between two remaining arms into.After weighing, by fork truck goods is transported again.This working method has been a hell to pay really.
Think in the past, a weighing-appliance is set in fork lift truck.Just weighing measurement is placed in the centre of support arm, and fork truck can also be worked fully normally, is very difficult with appropriate methods.
The designed weighing device of the present invention can address the above problem equally, its characteristics are, the scale pan is the loading end of fork lift truck, fork truck is by two fork-shapeds, be rigidly connected to each other by horizontal Beam, parallel, the support arm of roller has been installed at its end, be installed on the shaft guide head of front end and hinged with the lever of guide head and roller, the connecting link that is installed in the support arm is formed.Housing has constituted the base of fork lift truck, except that the centre position in the guide head back is provided with a weighing measurement device, has at least a weighing measurement device to be positioned at the centre of preceding each support arm of roller on it.
At least at the support arm place, near the weighing measurement device, connecting link is divided into the form of two bars, and these two bars are enclosed in the weighing measurement device that places the support arm center at a certain distance.
The invention will be further described with accompanying drawing below.Wherein:
The schematic top plan view of Fig. 1 weighing-appliance of the present invention;
The longitudinal profile synoptic diagram of Fig. 2 fork lift truck weighing-appliance;
The schematic cross section of the weighing-appliance that Fig. 3 is shown in Figure 2;
Fig. 4 has the side schematic view of the fork truck of weighing-appliance;
Fig. 5 vertical view;
Fig. 6 subassembly figure;
Fig. 7 support arm cross section enlarged drawing.
Fig. 1 has schematically represented a pan of a steelyard 1 and three three weighing measurement devices 5,6,7 that link to each other with it in vertical view.The weighing measurement device places housing Shang , And to make their line 2,3,4 constitute a triangle, obtains a stable three-point support like this.
The longitudinal profile synoptic diagram of Fig. 2 when being contained on the fork-shaped lifting loading-unloading vehicle that is used to transport the chassis by weighing-appliance of the present invention.Here the housing 8 and the scale pan 1 have only been expressed as base.
Lift fork-shaped pan of a steelyard 1 has been represented in transverse section shown in Fig. 3, horizontal Beam 9 and two are fixed together with it, the support arm 10 of arranged parallel spaced from each other, represented also that simultaneously constitutes the cover plate 11 that scale pan Yi Bu Fen And and the scale pan are fixed together, cover plate 11 is just schematically expressed the situation that it is fixedlyed connected with 10 with other parts 9 in the drawings.
(Fig. 2) placed three weighing measurement devices 5 with housing 8 fixed connections between two load Beam 12 that are made of the scale pan 1 and cover plate 11 and 13,6 and 7, their (see figure 2)s are connected with display unit with electronic computing units in a well-known manner.These two kinds of equipment itself do not belong to content of the present invention.
Especially represented as Fig. 5, in order to obtain weighing results accurately, weighing measurement device 7,5,6 places the centre of horizontal Beam 9, and the centre of each support arm 10 on fork truck 22, and as shown in FIG., they are far away as much as possible from getting each other.
Always have an arcs of recesses supporting 14 in mobilizable topworks in the weighing measurement device 7,5,6.In the arcs of recesses supporting, bulb 17 is arranged.The horizontal Beam of support arm 10 and base 8 covers by making the hood-shaped scale pan 1 accordingly.This scale pan has carrying plane below the position that weighing measurement device 7,5,6 is installed, wherein the arcs of recesses supporting constitutes the weighing measurement device 7 that is placed on horizontal Beam 9 and the support arm 10 and 5 carrying plane.Flat bearing plate 15 constitutes the carrying plane of settling weighing measurement device 6.In this way can compensate supporting precision and thermal expansion etc.
